It's actually even more complicated...

Remember, this is binary, so the only possible digits are 0 and 1. For example, 1/3 in binary is 0.01010101010101...;

Encoding that in "floating point", we first get:

1.0101010101 * 2^-2;

We can see that in this format, the first digit of the number is always 1; thus, the first digit of the significand, for any number, is ALWAYS 1 (in binary)! IEEE754 makes the optimization to not store this leading 1 as part of the fraction, so the the approximation to 1/3 is actually encoded as:

0 01111111101 0101010101010101010101010101010101010101010101010101

Ok but why are you posting this on Hacker News? Totally irrelevant.
I'd like to hear a version from someone who has been in the industry a lot longer too. I specifically added the section at the bottom explaining that I hadn't been in the industry all that long so I wasn't pretending to be speaking from a much more experienced position than I am. From the comments I've received so far there are definitely women who have been in the industry a lot longer than I have that share my point of view though.
I think the kind of defense you need to use depends on what kind of website you have.

Based on my experience if you have a small/medium website you won't find bots that execute javascript, understand a web page or use human spammers.

Those are reserved for the big ones, for all the others is mostly general-purpose bots that try every form they can find on the internet. Where speed is most important than accuracy spammer won't use the "Heavy" bots.

But is that sexism in the IT industry, or is that stereotyping in the larger community about the IT industry?
But if someone wants to reassemble individual sentences into paragraphs, as anyone knows who has tried to reassemble lines into paragraphs (as with an e-mail in its delivered form), it's nearly impossible to get right.

Is it? I haven't seen LaTeX do it wrong yet. Of course, I use actual formatting code to specify format -- what I'd give to someone else is the rendered document, not the LaTeX source.

Doom II is possibly my favorite game of all time. In the early-mid 2000s there was a pretty active multiplayer scene around a port called ZDaemon[1] and another called Skulltag. Conplete with a GameSpy-like client for finding and joining servers, new modes of play like CTF and monthly tournaments. Not sure what it's like today but worth a look if you're liking ZDoom.

John Carmack said no. “Story in a game is like story in a porn movie, he said. “It's expected to be there, but it's not important.”

I love this quote. I think many of today's AAA game designers need to take heed.
Expressing an opinion is considered "aggressive behavior" now? Ahahaha, oh feminists, you're so crazy. Anyway, you're saying that being female per se makes someone's opinion more valuable, which is a blatantly sexist opinion itself. Congratulations for shooting yourself in the foot and saying goodbye to what little credibility you had.

Meh.

I wasn't told it was a possibility either, and I'm male and went to an all male school. Depending on how old you are (I'm mid 30s now so school in the early 90s) and how behind the times your teachers were, I reckon it was pretty common for people not to understand that there was a career to be had in computers. This could be down to plain ignorance of how important they were going to become. I only realised it was an interest after starting and hating an engineering course in 96, because all school ever told me was 'here is a machine you can use to write documents and make pictures'.

Of course if the reason she wasn't told was because of her gender then sure, inherent sexism.
Hilarious!

Doesn't it get just RIDICULOUS reading some EBM stuff.
Also, what happens if you improve the UX and make new workflows but the profits don't materialize for some reason? Would you not get paid?

You could not talk in terms of profits (which could be eaten up by something else), but percentage reduction in unpaid invoices. Maybe look at reduction in overtime for AR staff, or number of invoices handled per staff member ("1.5 times as effective now!")

Apple agrees on licensing terms for use of iconic Swiss clock design

Nice to see Apple and SBB come to quick licensing terms on this. Apple was clearly infringing on the Swiss railway's clock design. Loved how the SBB opted for "an amicable agreement and compensation" as opposed to immediate legal action. You can't argue that the Swiss don't have class!
Unfortunately (at least in the UK) this technique cannot be used on consumer facing sites as it breaks the accessibility of the form for some disabled users.

For personal sites it really comes down to your preferences. Personally I would prefer that everyone was able to comment, however if it stops you having to wade through thousands of spam messages every day I can see the point of using it.
Set up a new Drupal site from the command-line with git and drush
Where is the evidence that EBM or SBM helps?
I recently set up a WP site and forum for a product my brothers are trying to sell.

We're not allowing commenting on WP, but obviously have to allow people to post on the forum. The forum software offered a couple of (unofficial) anti-spam plugins, but they were not effective at all.

Decided to try re-captcha, but found that to be equally ineffective (hadn't read about just how broken re-captcha is until this incident).

So I spent 10 minutes writing a little script that checks for mouse movement and clears a pre-populated field. If the field isn't empty, bot it is.

Wasn't sure it'd work, but so far, so good. I know it's not ideal and will be a problem for people without js enabled, but the site and product are targeting a demographic in which that's likely to be a rare occurrence so the benefit > risk.
There is certainly sexism in the tech industry. It's not terribly common or widespread, but it's there.

But the tech industry is also famously self-selective. Many people in the industry self-selected for it when they were pre-teens. Spending hours upon hours programming in BASIC or whatever on their C64s or TRS-80s before they were out of elementary school...before thoughts of sexism enter the consciousness. There is very little preventing young girls from getting involved with tech at a very young age except simple lack of interest.

Anecdotally, I remember growing up and horsing around with many friends on our 8-bit computers before any of us had 2-digit ages. As I grew up the friends and computers changed, but the basic demographic didn't. When my peer group hit puberty we would have killed a member of the peer group to get a girl involved in our group of nerds.

Many of my friends had sisters, none of their sisters cared the first thing about what we were doing. A few of their sisters showed some interest at times, but always seemed to have other priorities. This must be a shared experience as the type of group arrangement in the Big Bang Theory resonates with all of the tech industry males I know.

It wasn't until half-way through high-school that we finally lured a couple of girls into our group, but we spent most of the time teaching them basic computer skills than nerding out with them. Nevertheless I never heard anybody put the female members of our group down, or act like they weren't capable of eventually doing the high-nerd things that we were doing. To the person, everybody was helpful, and the girls hung around and one even tried her hand at majoring in CS...before changing majors to International Relations.

Happily, things have changed for the better. The number of women in tech has dramatically increased since those early days. It's not 50/50 by any stretch of the imagination. But there are actual women in tech these days doing cool things. They've self-selected to enter it and have put in the time to become good at it, and have managed to ignore the real sexism (such as it is) and that's very very cool.

It's an additional barrier that many males don't have to deal with, but I think self-selection at an early age is an even larger one.

I wonder if eventually people will just stop allowing hyperlinks in comments altogether. It would, at a stroke, eliminate the biggest incentive for spam.

Yes, it's nice (I guess) when someone's name is a link to their personal website or they can post the URL of a relevant article in the comments, but it's not like commenting ceases to be valuable without those features.
But the thing is that you can use proxies to study this to an extent.

Amongst rock climbers there is a naturally occurring population of free climbers, and it is possible to note the type and severity of injuries between different types of rock climbers (although i'm guessing your n is going to be low).

The safety of parachutes themselves is an interesting question because they're not used as a preventative mechanism, I think that's the primary difference between them and climbing ropes/harnesses/pitons.

Edit: I just noticed that I didn't address the randomized component. I'd still argue that evidence based medicine can actually include arguments that aren't randomized trials. That said, randomized trials are still one of the strongest sort of argument that can be made. As noted above, seatbelts are another sort of device that I don't think we need randomized trials to test the efficacy of.

This is a really unfortunate treatment of a serious topic. There are valuable insights, but the signal to noise ratio is too low.

To be clear, I'm not launching the "I didn't like your TONE"; I'm launching the "I didn't like how you trivialized and subverted your own argument".

To take just the first 3 points made:

1. Is the objection to the inclusion of a glossary? The serious criticism is that sexism is not rape, and makes it sound alarmist, though both are power displays. But to belittle the point by a solipsistic argument ( I don’t know about you but I haven’t exactly read a lot of news about rapes at web agencies lately ) only fuels people who would repurpose that line to say they haven't seen sexism at their company.

2. Is the objection to the inclusion of research? The serious criticism is that she rejects the exclusion of several self-collected data points, even if they have not been compiled by sociologists. But to subvert the point with a general aspersion to research at large ( Some research is great, but a lot of research is totally skewed to prove a point, and it’s not always easy to tell which is which ) only fuels people who would repurpose that line about the point trying to be made.

3. The serious criticism is that he has unsubstantiated assertions ( all women find a male-dominated industry “less appealing” and all-male groups less welcoming ), but the trivialization that immediately follows ( at the very least you need to preface them with ‘some research has found’ or ‘many women find that’ ) fundamentally denies the value that statistics, and empirical measurement, plays in social science.

It sounds like there's a kernel of something valuable, but the signal to noise ratio is too low. I'd love to re-read this after a few revisions.

This is really nice! If a project got accepted into Kickstarter, would it be better to stay with them or use this instead? The benefit of exposure to a large community as a Kickstarter project is pitted against the extra 5% that they take... How do you turn exposure into a monetary value for comparison? Pricing of ads maybe?
For smaller high density countries i would agree yes. For larger more spread out countries high-speed rail systems(assuming your referring to maglev) are simply to expensive at the current time.

I have no idea what you are referring to by tubes though.

Amazon has more or less said they were doing this since the beginning. It's a volume issue, the more you sell the cheaper they are, so you need to sell more to drive the cost down.

Amazon's goal is not to sell books, it's to be the place you buy everything, so it makes total sense for them to do this. Over the long term people will buy nearly everything online in some form or another, simply because it is more efficient in most cases to purchase digitally and have it shipped than it is to have huge stores like Best Buy that are basically giant warehouses that look a lot like stores.

Selling products that get people closer to that future makes Amazon more money per customer and that is good business.

I don't think that's what thisone was getting at. While I was growing up (late 80's into 90's), developing software and working on computers wasn't encouraged for a career path, for both boys and girls. It was always referred to as a hobby and one that wasn't looked upon very highly. Somehow I had a natural attraction to working with computers and software and that took me to where I am today working as a software engineer. My parents didn't even own a computer until I convinced them that I needed one for high school.

If I hadn't gone into software, I may have ended up in some other engineering discipline. Growing up I saw both boys and girls encouraged to go into engineering, but not into computers. Even as a male, I feel I'm working in software despite the culture I grew up with as a child.
This doesn't make a whole lot of sense to me. Maybe I totally missed the point somewhere, but as far as I can tell, it's basically saying that every airplane has an optimal speed for best efficiency, and going slower makes it worse, thus you can't make planes more efficient.

This totally ignores the possibility of using different airplane designs altogether. Build something whose optimal speed is slower, and you can make the whole thing more efficient.

Probably the best single-number measure of aerodynamic efficiency is the lift-to-drag ratio. For most airliners, 787 most likely included, this ratio is in the low 20s. The best machines out there are in the 70s. Of course, they fly slow, which is a tradeoff airliners don't want to make, but it shows that there's plenty of room for improvement.

Can we build a more efficient airplane? Of course! But we may not want to.

Gloria Steinem once remarked that women in our culture are valued when they are young and pretty, while men in our culture are valued when they are old and rich: therefore, as they grow older, women become more radical and men become more conservative.

(As a man, I thought this was a very insightful observation... when I first read it... many years ago. :-)
About aggressiveness: It turns out that when women act aggressive, they are often treated differently than men who act the same way. This is a perfect example of where unconscious biases fuck up the system.

This is something actual research has been done on, though I don't have any links handy. :(

Okay but it's weird to jump straight to AWS when the exact complaints are the strengths of a parallel platform on the same cloud provider. It would be like if someone were saying they were leaving Windows for OS X because Windows is not open source, and totally ignored the existence of Linux. I'd say commenters would be within their rights to bring up the elephant in the room without being accused of shilling.
In general, trying to sell content on the web is problematic. Lots of people who'll be willing to pay $1.99 a month for this by clicking a button, knowing that they can cancel the subscription trivially (and will be reminded by Apple that they have it every month), will not be so happy to pay $1.99 a month where they have to spend time filling in a credit card form, with considerable uncertainty about how they can cancel.

Actually, the sophisticated bots typically target platforms, not websites. So if your website runs Wordpress, you're much more likely to be spammed hard than if you custom-built a comment form.
This seems overly pessimistic to me. While doubling efficiency may be impossible 10% is far too low as an estimate without a fairly short timeframe.

Weight reduction - Reduce the weight and you can reduce the air you need to move.

There are also conceptual designs for integrated wing aircraft that if they were easier to make and could be made to work with current airports might have further real gains.

These added to the engines and other factors mentioned probably make at least a 40-50% improvement possible (although not necessarily easy or quick to achieve).

This doesn't break the concepts explained or mean that there is unlimited room for improvement but 10% is not going to be the limit by a long way.

Just because she didn't write as if her blog were an academic journal doesn't mean she isn't giving a serious topic the treatment it deserves. Her post exists to state that "the whole [.net] article is hyperbolic generalisation."
This hits the nail on the head in my experience. As "technical" people (I think that describes most HN readers) it is common to find ourselves working with at least a few people who are less adept at various technologies. In some cases this doesn't really make a difference, but I have often found it to be very frustrating.

A boss or coworker who can't use a computer is largely forgivable. A boss or coworker who refuses to learn is hard to respect and, by extension, hard to work for or with.
Nice idea, but can you detect mouse movement if the user is using a tablet?
iOS is probably the easiest platform on which to do a subscription publication and reach a large audience. People are often unwilling to pay for subscription content on the web because they have to fill in a credit card form, and there can be problems with cancelling, and Android's subscription magazine thingy is US-only.
Since when is it ok for a US official to talk about China and Russia as "adversaries"?
The Imaginary Teacher Shortage
The central argument of the article seems to be that an air plane must spend energy for drag an lift, and there's a limit to how good you can get at those.

That's all fine in the current model, but other modes of transport are thinkable. For example an airship that doesn't need to spend energy on the lift, or a ballistic transport model (think ICBM) that uses flight parabolas around the curvature of the earth.

Ok, you probably wouldn't call their "airplanes" anymore, at least not by traditional terminology.

Update: oh, and you can always try to improve the constant factors involved, like the total aerodynamic drag and weight

Great quote. I try to convey this to people. Melvin Van Peebles didn't complain that blacks were underrepresented in Hollywood. He just went out and made Sweet Sweetback's Baadasssss Song (and it wasn't easy). That movie ushered a new era of black cinema. He solved the problem by doing, not pontificating.

I'm not saying there's no room for talking, but at this point no one is bringing anything new to the table; I'm saying if you want to solve a problem do something about it. Lead by example.
